股票代码以XD开头的意思是该股票在除息日进行除息交易。除息日是在权益分配日之后，当公司分配红利、股息等权益时，会进行除息交易，以调整股票的价格。

在除息日，股票的开盘价通常会比前一个交易日的收盘价低，这是因为公司会从股票价格中扣除红利或股息。对于持有该股票的投资者来说，他们的股票价值会减少，但同时他们也会收到相应的红利或股息。

除息日对于投资者来说是一个重要的日子，因为他们需要了解自己的投资组合的价值可能会受到影响。在进行投资决策时，投资者应该考虑公司的经营状况、行业前景、市场情况等多个因素，以做出明智的投资决策。

The stock code starting with XD means that the stock is performing a dividend distribution on the ex-dividend date. The ex-dividend date refers to the day after the equity distribution date, when the company distributes dividends or stock dividends and performs ex-dividend transactions to adjust the stock price.

On the ex-dividend date, the opening price of the stock is usually lower than the closing price of the previous trading day, because the company will deduct dividends or stock dividends from the stock price. For investors holding this stock, the value of their investment portfolio will decrease, but at the same time they will also receive the corresponding dividends or stock dividends.

The ex-dividend date is an important day for investors because they need to understand that the value of their investment portfolio may be affected. When making investment decisions, investors should consider multiple factors such as the company's operating status, industry prospects, market conditions, etc., to make informed investment decisions.
